  <name>beta-Humulene</name>
  <description>Beta-humulene belongs to the class of organic compounds known as sesquiterpenoids. These are terpenes that contain 15 carbon atoms and are comprised of three isoprene units. The biosynthesis of sesquiterpenes is known to occur mainly through the mevalonic acid pathway (MVA), in the cytosol. However, recent studies have found evidence of pathway crosstalk with the methyl-eritritol-phosphate (MEP) pathway in the cytoplasm (PMID:23746261). Farnesyl diphosphate (FPP) is a key intermediate in the biosynthesis of cyclic sesquiterpenes. FPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. Beta-humulene is possibly neutral. It is detected in allspice and guava fruit, celery seed, lemon oil and spearmint leaf ( http://www.thegoodscentscompany.com/data/rw1539551.html#tooccur ).</description>
